VR Headsets are one of the most fun things that you can do with your PC or Stand Alone, provided you have the right headset.
"Virtual reality is a fascinating way to travel using nothing more than the power of technology. With a headset and motion tracking, VR lets you look around a virtual space as if you're actually there, or play a game as though you're in it. "
Oculus Quest 2 is rated as OUTSTANDING.
I have an Oculus Quest 2 Headset and I can tell you it is one of the best VR Headsets out there. I can tether to my PC or I can do stand alone.
